Thanks all for your suggestions. Adding self. before calling my functions fixed that issue. I'm now running into a different issue where the stored procedure I am using isn't getting properly read into the pandas dataframe. I don't get any errors, the tkinter window pops up like it should, but when the PDF gets generated, there is no data in the rows, just the column names and other formatting I've written in.
I added print(df) to the code to check if it was an issue with the data getting read from the dataframe to the PDF, but print(df) just returns Empty DataFrame.
